In reading the numbers back, they are being rounded to 18 decimal digits of precision:
use warnings;
for(10.1, 10.2, 10.3, 10.4, 10.5, 10.6, 10.7, 10.8, 10.9) {
printf "%.18g\n", $_;
}
__END__
Outputs:
10.0999999999999996
10.1999999999999993
10.3000000000000007
10.4000000000000004
10.5
10.5999999999999996
10.6999999999999993
10.8000000000000007
10.9000000000000004
I don't know why that is happening or how to influence the result, but you clearly want those numbers to be rounded to 3 decimal digits of precision:
use warnings;
for(10.1, 10.2, 10.3, 10.4, 10.5, 10.6, 10.7, 10.8, 10.9) {
printf "%.3g\n", $_;
}
__END__
Outputs:
10.1
10.2
10.3
10.4
10.5
10.6
10.7
10.8
10.9

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
